[Andrew Morton]

The patch titled
     Subject: drivers/base/node: rename __register_one_node() to register_one_node()
has been added to the -mm mm-new branch.  Its filename is
     drivers-base-node-rename-__register_one_node-to-register_one_node.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/drivers-base-node-rename-__register_one_node-to-register_one_node.patch

This patch will later appear in the mm-new branch at
    git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews.  Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.

Before you just go and hit "reply", please:
   a) Consider who else should be cc'ed
   b) Prefer to cc a suitable mailing list as well
   c) Ideally: find the original patch on the mailing list and do a
      reply-to-all to that, adding suitable additional cc's

*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***

The -mm tree is included into linux-next via the mm-everything
branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
and is updated there every 2-3 working days

Subject: drivers/base/node: rename __register_one_node() to register_one_node()
Date: Wed, 28 May 2025 12:18:04 -0500

The register_one_node() function was a simple wrapper around
__register_one_node().  To simplify the code, register_one_node() has been
removed, and __register_one_node() has been renamed to
register_one_node().
